Application filed September 14, 1914. Serial No. 861,720.

To all w 7mm it may concern:

Be it known that I, NOAH C. Nnnson, a citizen of the United States,residing at Imperial, in the county of Imperial and State of California,have invented new. and useful lmprovements in ombined Harvesters, ofwhich the following is a specification.

This invention is an improved combined harvester, especially adapted.for harvesting ipe wheat, barley and other similar grains, the objectbeing to provide a machine that is lighter and simpler in constructionthan the ones now in use for that purpose.

The invention consists in the construction, combination and arrangementof devices hereinafter described and claimed.

The primary object of my invention is to construct a combined harvesterwhich eliminates all cutting machinery usually carried by a machine ofthis character thereby simplifying the construction. and producing amore compact and eiiicient device; and my invention consists of thenovel features here in shown, described and claimed.

In the accompanying drawings:

Figure 1 is a side view of a combined harvester constructed. inaccordance w ith my invention.

Fig. 2 is a plan view of the same.

F 3 is a perspective detail sectional view of the two cylinders and thereel-belt for making the grain lean backward toward the cylinders.

In accordance with my invention 1 provide a frame-work #7, in whichoperate threshing and lifting cylinders 1 and 2, the concave #3, andgrain-carrier #6, which must travel in the direction the arrows point. Aset of screens or sieves 11 separate the chaff from the grain ashereinafter more fully described. A grain auger 12 mounted in positionbelow the screens 11 carries the clean grain out to the sacker (notshown) mounted on the platform 20. The auger 13 which empties into thereturn elevator 14, which in turn empties into a spout 15, returns theincompletely threshed grain to the cylinder 1. 16 represents anincasedfan or blower which blows the chaff out while the grain passesthrough the screens 11. 17 represents a brace or support which isadjustable to adjust the reel belt 10 to suit the height of the grain.

18 is a pivotal arm that supports the front end of the reel belt 10 andby virtue of the brace 17 is raised or lowered to adjust said cylinder1.

reel belt as hereinbefore described. 19 rep resents a supporting wheelfor the front end of the machine. said wheel being adjustable to varythe distance of the machine frame7 from the ground. 8 and 9 representthe sprocket wheels over which the chains carrymg the reel belt 10travels. 4 represents a removable casing placed over the cylinderl toprevent the grain from wasting.

5 represents the transverse supporting shaft which is journaled to theframe 7 of the machine and upon which the traction wheels 25 are keyedby means of ratchets, said wheels 25 carrying the weight of the machine.A sprocket wheel 28 is keyed to the shaft 5, which through the medium ofa. chain drives the gear 22, which in turn drives the spur gear 24:keyed upon the shaft upon which the cylinder 1 is mounted. Thearrangement of the gears and spurs is such that the shaft 5 drives thecylinder 1 at a high rate of speed.

The drive wheels 25 are connected to the shaft 5 by a dog and ratchetarrangement, (not shown) so that on turning the machine the outsidewheel, which rotates faster than the inside wheel, will drive the gearsand The ratchets are arranged to allow either drive wheel to idle whenbackingand to rotate the shaft 5 when going forward.

In Fig. 2 #20 represents the extension of the frame-work of the machinewhich forms a. platform by boarding it over, upon which thedrivers seatand the sacker is placed, but not shown in the drawing. #21 representsmeans for connecting the machine to the engine when engine power isused, or horses when. they are used.

The reel-belt 10 must be driven in the direction of the littlearrows andat a rate of speed equal to'about twice the rate the machine movesforward over the ground, the movement thereof tending to force the grainback in position to be received by the cylinders 1 and 2.

The cylinder #1 must be driven at a high rate of speed in the directionof the arrow. Cylinder #2 must be driven in the opposite direction at amuch slower rate of speed. The cylinder #2 is used to lift the grainwhen it is badly lodged or down as it is called.

The cylinders #1 and #2 and the concave #3 are secured in a unit whichis not shown in the drawing as it is immaterial in what and 28 andforming an endless belt. The

shaft 29 is mounted in the extreme front end of the frame and carriessprocket wheels 8.. Side bars 18 are pivotally niountedupon the shaft 29and extend forwardly in substantially horizontal parallel planes. Theshaft 31 ismounted in the forward ends of the side bars 18 and carriesthe sprocket wheels 9, and the reel belt 10 is mounted with the chains27 and 28 running over the sprocket wheels 8 and 9. The sprocket Wheels9 are considerably larger than the sprocket wheels 8 and form theextreme front portion of the machine, and the reel belt 10 is connectedand operated so that the'slats move downwardly at the extreme front ofthe machine and backwardly on the lower side, so as to catch the tops ofthe grain and bend them toward the machine. The cylinder 2 is mountednear the forward end of the frame-work 7 and has teeth, the

ends of the teeth being, close to the slats of the reel belt, and thecylinder 2 is'operated with theteeth moving upwardly on the forward sideso that as the heads of the standing grain are carried toward thecylinder 2 by the reel belt 10 the heads of the lodged grain are liftedfrom the ground by the cylinder 2 and the mass is carried to the concave3 where it is thoroughly threshed, the chaff and grain falling upon thecarrier 6. The braces 17 are connected to the'pawl wheel shaft 32, andthe pawl wheel 33 fixed upon the shaft 3:2 is engaged by'a pawl 34: soas to sustain the weight upon the shaft 31 and so as to adjust the shaftup and down for high or low grain. The braces 17 are preferably leatheror canvas straps wound upon the shaft 32.

' Special attention is called to the factthat I have produced aharvester comprising a carriage, an endless slatted belt construct onpivotally connected to the forward end of Copies of this patent may beobtained for the carriage and extending forwardly, a

making it possible to pull the heads of wheat and other similar grainfrom the stalks, thresh the heads, and discharge them to a conveyer, andthereby doing away with the necessity of cutting, handling, and

threshing the stalks and weeds and grass.

What I claim and desire to secure by Letters Patent of the United Statesis:

1. In a harvester, a suitable carriage, a threshing cylinder mounted inthe carriage. a threshing concave mounted below and in opposition to thethreshing cylinder, a lifting cylinder mounted directly in front of theconcave and in opposition to the threshing cylinder, and an endless reelbelt construction mounted with its rear end close to the passage betweenthe two cylinders.

2. In a harvester, a suitable carriage, a threshing cylinder mounted inthe carriage, a threshing concave mounted below and in opposition to thethreshing cylinder, a lift ing cylinder mounted directly in front of theconcave and in opposition to the threshing cylinder, a pivoted frameconnected to the front end of the carriage on a line with the passagebetween the two cylinders and extending forwardly, means for adj ustablysupporting the forward end of the frame. and an endless reel beltmounted. to travel in the frame.

In testimony whereof, I ai'lix my signature in the presence of twowitnesses.

NOAH C. NELSON.
